Medvedenko said he decided to sell the rings after going to the roof of one of the tallest buildings in his Kyiv neighborhood and watching rockets launched by Russian forces streak through the night sky. “In this moment I just decided, ‘Why do I need these rings if they’re just sitting in my safe?’” Medvedenko said. “I just recognize I can die. After that, I just say I have to sell them to show people leadership, to help my Ukrainian people to live better, to help kids.”
